WARD W. LINCOLN, OF ROCK FALLS, ILLINOIS.

FOOT-SCRAPER.

To all whom it may concern:

Be it known that I, WARD W. LINCOLN, a citizen of the United States,residing at Rock Falls, in the county of Whiteside and State ofIllinois, have invented certain new and useful Improvements inFoot-Scrapers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention has reference to foot scrapers, and is specially designedto be used in connection with concrete walks, the device be ing placedin position during the construction of the walk.

The preferred form of my device, and one modified form thereof, areshown and de scribed herein, to which particular constructions I do notwish to be understood as limiting myself, as other changes in the formthereof can be made without departing from the spirit of the invention.

In the drawings: Figure 1 is a perspective, showing my invention as itappears when in use. Fig. 2 is an end view of the device. Fig. 3 showsthe lower face thereof, with the device inverted. Fig. 4 is a plan viewof a modified form of my invention. Fig. 5- is a vertical cross-sectionin the line :c:c of Fig. 4.

Similar parts are representedby corresponding numerals throughout theseveral figures.

The device comprises a casing having a sloping bottom plate 1, and endplates 2.

3 is a scraper blade, held in recesses e in the inner faces of theplates 2, such plates being provided with enlarged portions 5, to permitthe forming of the recesses. On their outer faces the plates 2 areprovided with ribs 6 and flanges 7 connecting therewith,

and on the lower face of the late 1 a rib 8 extends longitudinallythereo 9 represents a portion of one edge of a walk in which the deviceis secured.

The invention is placed in position during the construction of the walk,and while the concrete of which the walk is formed is in a plasticcondition, the upper edges of the plates 1 and 2 being flush with thetop sur- Specification of Letters Patent.

face of the walk, and the side edges of such plates being even with theside facing of the walk. The spaces on each side of the ribs 6 becomefilled with the cement, so that when the same has thoroughly hardenedthe device is locked from upward or outward movement by the ribs 6 andflanges 7. hen the foot is applied to the scraper, when in use, thepressure tends to force the plate 1 downwardly in its bed, but thistendency is overcome by the ribs 6, and also by the rib 8 on the lowerface of the plate.

In Figs. 4 and 5 is shown a construction of my device wherein the plate1 is provided with an opening 10, in which is held a pro jecting portion11 of the concrete, which aids in holding the plate 1 from lateralmovement.

In thisform of the device the rib onthe lower face of the plate 1 isextended around the edge of the opening 10, and the walls of the openingare upwardly flaring, preventing the strip 11 from becoming disengagedfrom the plate.

The scraper bar 3 is preferably inclined outwardly, as shown in thedrawings, to facilitate the operation of cleaning the shoes, and asufficient space is left between the lower edge of the scraper and theplate 1 to permit the device to be easily cleaned.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is:

1. A device of the class named, comprising an inclined bottom plate apair of end plates, integral therewith; engaging ribs on the outer facesof said end plates; and a scraper-bar, fixed at its ends in said endplates, so as to leave a. space between said bar and the bottom plate,substantially as shown and described.

2. A device of the class named, comprising a bottom plate, provided onits lower face with a longitudinal rib; a pair of end plates, integraltherewith, and provided on their outer faces with engaging ribs; and ascraper bar, supported at its ends in said end plates, substantially asand for the purpose set forth.

In testimony whereof, I affix my signature, in presence of twowitnesses.
